原始语种摘要: Carbon cycling in the Amazon is closely linked to atmospheric processes andclimate in the region as a consequence of the strong coupling between theatmosphere and biosphere. This work examines the effects of changes in netradiation due to atmospheric aerosol particles and clouds on the netecosystem exchange (NEE) of CO2 in the Amazon region. Some of the majorenvironmental factors affecting the photosynthetic activity of plants, suchas air temperature and relative humidity, were also examined. An algorithmfor clear-sky irradiance was developed and used to determine the relativeirradiance, f , which quantifies the percentage of solar radiation absorbedand scattered due to atmospheric aerosol particles and clouds. Aerosoloptical depth (AOD) was calculated from irradiances measured...
